Model 8400 Magnum Classic The Kimber Model 8400 Magnum Classic has been designed with a 26-inch steel barrel that benefits from a matte blue finish and a sporter contour. It comes with a checkered A-grade walnut stock that has a hand-rubbed oil finish and sling swivel studs. In addition, this stock benefits from other features, such as the steel grip cap, the sling swivel studs and the Pachmayr decelerator recoil pad (1-inch thick). The manufacturer fitted the unit with a 3-position Model 70-type safety and a Mauser claw extractor.
